To test the factorial validity and reliability of the Primary Care Assessment Tool adapted to Oral Health, adult patient version, an instrument used to verify the presence and extent of attributes in Primary Health Care services.
Population-based cross-sectional study using conglomerate random sample carried out in Primary Health Care Dental services in Porto Alegre between 2011 and 2013. We interviewed 407 adult patients who used Primary Health Care Dental services. Construct validity was tested through factorial validity and reliability of the Primary Care Assessment Tool, that comprises 81 items distributed throughout Primary Health Care attributes. Equamax orthogonal rotation method was used in the factorial analysis; and, in order to assess reliability of each component, we used the item-total correlation and the ratio of success of the scale.
In the factorial analysis, 10 factors were retained, explaining 53.3% of the total variation. This result demonstrates the multidimensional structure of the instrument. The reliability assessment showed Cronbach's alpha values ranging from 0.39 to 0.89. For the success of the scale most of the results (eight of nine attributes) were greater than 85%.
The instrument is valid for the assessment of oral health services in Primary Health Care from the perspective of adult patients, as well as for monitoring and evaluation of oral health services in Primary Health Care attributes and comparative studies.
检验适用于口腔健康的成人患者版初级保健评估工具的因子效度和信度，该工具用于验证初级卫生保健服务中属性的存在及程度。
采用整群随机抽样的基于人群的横断面研究，于2011年至2013年在阿雷格里港的初级卫生保健牙科服务机构开展。我们对407名使用初级卫生保健牙科服务的成年患者进行了访谈。通过初级保健评估工具的因子效度和信度检验结构效度，该工具包含分布于初级卫生保健各属性的81个条目。因子分析采用等量正交旋转法；为评估各分量表的信度，我们使用了项目与总分的相关性以及量表的成功率。
在因子分析中，保留了10个因子，解释了总变异的53.3%。这一结果表明该工具具有多维结构。信度评估显示，克朗巴哈系数值在0.39至0.89之间。对于量表的成功率，大多数结果（九个属性中的八个）大于85%。
从成年患者的角度来看，该工具对于评估初级卫生保健中的口腔健康服务是有效的，也适用于监测和评估初级卫生保健属性中的口腔健康服务以及进行比较研究。
